Also of interest are the 22.214.171.124 OLE Property sets (in [MS-OSHARED].pdf in the zip file from the page linked above). We might be getting some of those already, couldn't hurt to double-check though. The following subsections (up to 126.96.36.199.3.2) are also interesting.
188.8.131.52.1 PropertySetSystemIdentifier might also give a bit of information (OS).

I wonder if the applicationCIsid in the DocumentSummaryInfoStream (page 146 in the above-mentioned document) is really always all-zeros, or if there is a unique identifier for the Office installation in there. We should check...
would seem to give a way to find the CISID of locally installed apps. Given that bit pattern, we could then just check if a file created on the system contains the pattern at all (this might depend on the specific Office version, maybe only older versions used this?).
